wxman57 wrote:I don't expect it to do much for the next couple of days due to its very fast west movement. Should be a TD by Wednesday and a TS as it enters the NE Caribbean Wednesday night. Near the Bahamas next Fri/Sat, quite possibly as a hurricane. Beyond then, who knows? Models indicate a trof off the East U.S. Coast next weekend. If it's stronger, it could be steered north, missing the US to the east. For now, I'd put my money on a Carolinas hit early next week. Way too far out and very low confidence on that forecast, though. I think if it's slower to develop and is weaker, then a more westerly track, which could take it to the NW Caribbean in 7-8 days.


I really hope it evades the NE Caribbean because the islands have gone thru a lot lately with Irma and Maria and of course dealing now with covid-19.There are still parts of some of the islands that not recovered yet from the hurricanes like here in PR where believe it or not there are over 30,000 homes with blue tarps.

Bastardi in his update last night suggested this will become a storm. He added looks to be a split in the trough coming which could provide a path into the SE states. He was not too specific but it looked like he was pointing to the NE Florida to SC area for a potential impact. Today's PM plots off Tropical Tidbits seem to show a turn straight north before 75W. IMO, this far out, no need to get overly concerned especially with models veering more from a US over past 24 hours.

I must say that is one of the largest Circulations I have ever seen lol

if it ever did become a hurricane .. you better bet it would create its own environemnt

It takes up 3/4 of the Atlantic between Africa and the Islands

Does its large circulation make it more susceptible to dry air and SAL intrusions?

It has plenty of moisture options. so I would imagine dry air would not last long around it..

It's large size is going to probably hinder it consolidating in the near short term, but once it gets going, watch out.

Looks very healthy for being only an "invest."

In the longer term, 92L is going to be moving through some pretty steamy SST's. While Hanna did a number on the northern gulf, pretty much all of the water in the short term ahead of 92L is running around 1 degree Celsius above normal. If this ever does become an east coast threat the waters are absolutely primed, especially a little further north with SST anomalies running 2-3+ degrees above normal. The 26 degree isotherm is even further north than long Island, so any system tracking nearby would get some serious fuel. Dry air and forward speed, not ocean temperatures, will (hopefully) be the main dampeners of the system.

This afternoon there’s been an increase in intense thunderstorms near the designated center, which is interesting since we are not in the diurnal maximum yet. Take a look at the last frames:

Large circulation means it has a shallow pressure gradient.
Convection firing closer to the ITCZ tonight might be the latitude for an eventual low level center.
Models are pretty much a Rorschach Test, and I never did very well on those till somebody points.
The current recurve trend in the models will swing left if the system stays weak and south.

That would be great if the first Cape Verde hurricane recurved and stirred the coffee leaving a peak season kink in the Jet stream. The current mid Atlantic ridging is bad news.

This invest is HUGE by Atlantic standards. Looks like something straight out of equatorial WPAC.

It's almost as if the Atlantic and WPAC swapped basins. Record activity in the Atlantic came with the record inactivity of the WPAC.

I totally agree - that's a huge circulation. Gut feeling is that we will have to watch this one closely.

Some potential analogs for 92L are Emily (2011) and Bertha (2014). Very similar time of year and potential track.

I keep having to remember...its JULY, not SEPTEMBER!
It's not normal to be expecting Cape Verde development

We do not mention that last one here! That ugly mess can just be forgotten and never heard of again.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.
